T/w z pc'wrz'ting wwclzanism.-In the companying drawings, referring to Fig. 1, there is shown a typewriting mechanism of which 1 indicates the keys and key-bars. 2 is the spacing key of the typewriting mechanism, and 3 is a spacing bar controlling the escapcment mechanism of the typewriter carriage. 4 is the frame of the typewriter carriage, in which is mounted a platen 5. Means are provided for manual rotation of this platen, as in line-spacing, and also mechanical rotation in line-spacing, where a record is being made by the printing devices of the adding mechanism of the machine. An escapementbar is provided whereby the carriage may move step-by-step laterally in lettercr figure spacing, and tabulating keys 1:? are provided whereby the carriage may be arrested at predetermined lateral positions for work of tabulation.

The typewriting mechanism of my present machine may, in addition to the essential features of such a mechanism, heretofore de scribed, also be provided with such additional featurcs as may be desired or useful.

I deem it unnecessary to give a more detailed description of the typewriting mechanism here, as a reference to the before-mentioned patent will give a full and clear explanation of the same.

The adding mecham'sm-.-The keys in group A (see Fig. 2) which are identified with the adding mechanism, are connected to a series of bars a which are mounted upon a common pivot 21, said bars to the rear of said pivot having their ends deflected so as to lie in a straight line under a longitudinal row of independent vertically movable bars 50 which cooperate with the setting-up pins (33 of the carriage 57. The rear ends of these bars la cxtcnd under a plate 22 pivotally mounted in the free end of yoke frame 23 which has a forward extension 25 arranged above the spacing bar 3 of the typewriter. In this manner the operation of any of the keys in group A will depress the bar 3 and actuate the escapemcnt mechanism of the typewriter carriage, causing the carriage to move laterally step by step a number of spaces equal to the number of figures set up on the keys of group A. The operation of the carriage escapement from the keys in group A is particularly useful in lineal addition as it is only necessary to strike the space key once after the printing of each number.

Means are provided for locking the carriage against lateral movement in order that vertical columns of figures may be printed, buv it is unnecessary to describe these means here in detail. Means are also provided for rotating the carriage in the operation of printing numbers one under the other in column formation, but it is unnecessary to describe such mechanism here as the same is fully set forth in the before-mentioned patent.

ontrolling the position of the forward tozalizcrs from the typewrizing carriagc. Referring to Fig. 8, 39 indicates a bar which is carried by the typewriter carriage and whose rear end is provided with a series of notches in which may be adjustably mounted a series of blocks 40. There are preferably two of these adjustable blocks 40 which are designed to cooperate with a tappet 45 mounted on a sliding bar 46. This bar is connected at its rear end to an escapement lever "47, which escapement lever, when vibrated, permits the forward totalizer, which may be in position over the acuating devices, to move from left to right to one side of, and out of position with respect to, said actuating devices. The purpose of having two adjusting blocks 40 on the laterally movable paper carriage is to enable the operation of the tappet45 twice as the carriage moves leftwardly. \Vhen the carriage is in its normal position at the left, the lowermost totalizer is in position to be moved horizontally over the actuating devices and will thus be capable to operation until such time as, in the leftward movement of the carriage the first block 40 cooperates with the tappet 46, which will disengage the lowermost totalizer, move the totalizers downwardly and 'place the second or middle totalizer in cooperative relation with the actuating devices. In order to disengage the middle totalizer and place the third or uppermost totalizer in cooperative relation with the actuating devices, the second block 40 is necessary. The two blocks are made adjustable so that the selection of a desired totalizer may be automatic in any predetermined leftward position of the paper carriage; 49 are two frame plates pivoted at their rear ends on a shaft 50 mounted in the frame of the machine. 500 is a frame pivotally mounted upon the shaft 50, preferably adjacent one of the frame plates 49. This frame carries a vertically disposed segmental plate 501 at its forward end in which are slidingly mounted shafts 502 of the several groups of totalizer wheels. These shafts also pass through a curved slot formed in a segmental extension 49 on the adjacent frame, plate 49. Each shaft 502 is provided with a collar 503 at its outer and designed to be embraced, when. the selected totalizer is in the horizontal plane to be moved laterally over the actuating devices, by a grooved block 504 on the upper end of a lever 505. This lever is pivoted to the frame of the machine at 506 and is conndcted to a spring 507 which tends to draw the upper end of said lever outwardly away racks 100 by a slot-pin connection.

from the actuating devices and move the set of totalizer wheels controlled thereby out of operative relation, and to one side of, said actuating devices. The lower end of lever 505 is provided with a bell crank extension 505 to which is connected a linlf 508, preferably given a quarter turn, and in whose lower end is arranged a slot- 508 for coiiperating with a pin 509 on the end of an arm 509 mounted on the shaft 6. This shaft 106 has fixed to it the arm; which carry the reciprocating bar 104 for returning the arms 102 connected to the One of the arms 105 which, with the bar 104, constitutes the reciprocating frame, is provided with a pin 107 fitting in the .cam slot in cam 108 mounted on the shaft 81. The shaft is re" d at each operation of the handle of the ,achine, and in its first movement the frame 105 is not actuated, but whenv the pin 107 rides in the fluctuation of the cam groove, the frame 105 is moved for ward to permit the racks 100 to move forward, after which the lower concentric portion of the cam holds the frame 105 in its forward position. It is during the forward movement'of the racks that thepin 509 rides upwardly in the slot- 508 until it contacts with the upper end of the slot, when the lever 505 is rocked so as to move the totalizer engaged by the grooved block 504 thereof leftwardly over the actuating racks. This upward movement-of the arm 509 is effected by means of a cam 266, see Fig. 1,

- which operates upon a roller upon the end of'an arm 509 fixed to arm 509. In the position of the parts shown in Fig. 4, which is the normal position of the parts, the lowermost group of totalizer wheels is connected to the grooved block 504, and, after an example has been set up on the keyboard of the machine and the stops 93 positioned upon the initial movement of the handle, the racks 100, carrying type 148 at their outer ends, under the impelling action of springs103, will be moved forwardly, when permitted to do so by the reciprocating bar 104, until arrested in their intended position. Of course the bar 104 will permit the racks 100 to move forwardly a distance of nineteeth if such is their intended movement, and it is-during this movement of the racks that the lever 505 is rocked. The totalizer wheels, however, are so positioned that they do not interfere with the forward movement of the racks, said totalizer wheels being in a horizontal plane above the teeth of the racks so as to be meshed therewith. When a totalizer is moved over the racks, the escapement lever 47, heretofore referredto, will move forwardly and drop into a V-shaped groove 502 in the outer end of the totalizer shaft (see Fig. 7) and hold said to talizer over the racks until the escapement need not be here described in detail.

block 40 on the paper carriage vibrates the lever 47 to release the shaft, whereupon the spring 507 will retract the group of totalizer wheels, moving said group laterally out of position with respect to the actuatlng racks. A segmental extension 501 on the forward end of frame 500, heretofore referred to, is provided with totalizer locking bars 510 which extend slightly beyond the totalizer. wheel of highest order, as shown 1n Fig. 8. The forward bar of each set of totalizer wheels alines with a plate 511 arranged upon a stationary bar 512 which connects the forward ends of the frame plates 49, and upon which bar are also mounted the, pendants 121 of the carrying mechanism. A plate 513 is provided with a shoulder 513 which registers "with the totalizer locking bar 510. Plate 513 is likewise secured to the side frames 49. In this manner, whenever any one of the totalizers is out of position with respect to the actuating devices, it is held against movement by the bars 510 arranged on each side thereof, and when said totalizers are brought into position the bars 510 register with the plates 511 and513, so that, when the totalizers are moved over the actuating racks, they will ride upon said plates. These plates are preferably slightly beveled, so as to guide the teeth of the totalizer wheels thereon. Each totalizer shaft is provided with a winged hub 514,, the wings ofwhich ride upon the bars 510 in a manner similar to the totalizer wheels,

centering recess into which fits a cone bearing 513 extending from the bar 513. "The" totalizer wheels are indicated at 119, they being confined between the hub 514 and a collar 502 on the inner end of the shaft wheels with the rack, is the same as set forth in the aforesaid application and patent, and

mally, the parts are in the position shown in Figs. 8 and 11, wherein the lowermost group of totaiizer wheelsis in a position to be moved laterally over the actuating racks. A segmental plate which carries these groups of totalizer wheels is supported by a pawl 515 on the lower end of a lever 516, pivo tg-lly mounted upon one of the frame plates 49 so as to be movable therewith. The upper end of this lever passes between pins 46 and 46 on the plate 46' which is connected to the escapement lever 47 (see Fig. 7) so that the lever 516 will be operated whenever the escapement lever is operated. A pin 517 is arranged-on'the lever 516 adjacent the forward .edge'of the (See Fig. 8.) The manner of depress, ing the frame 49 to engage the totalizer' Nor- segmental head 501 of the frame'500. The forward edge of this segmental head is provided with notches 501*, as shown, and whenever the lever 516 is rocked, the pin 517 moves under the upper shoulder of a notch 501 and the pawl 515 is withdrawn from the lower edge of the segmental plate (or from the upper shoulder of a notch, as the case may be), the parts being thus held (see Fig. 12) until the escapement lever is released, when the pin 517 will be withdrawn from its shoulder and the pawl .515 will be moved inwardly against the edge of the segmental plate in readiness to engage the next adjacent notch above it, when the totalizers descend. (See Fig. 13.) A spring may be provided to assist the downward movement of the totalizers, but ordinarily gravity will sufiice. From the position of the parts shown in Figs. 8 and 11, the lowermost totalizer will be moved out of position and the next adjacent totalizer above it moved into position with its collar 503 embraced by the grooved block 504, whereby this totalizer is placed under control of the lever 505 and in position to be moved over the p by the bars 510, :f t

actuating devices. (See Fig. 13.) The next vibration of lever 516 will place the third or uppermost totalizer under control of the lever 505. When the escapement lever is operated, the totaliner in position over the actuating racks is in mesh with 'the carrying sectors 129, coincident with the release of the shaft 502 by i'th'd disengagement of the groove 502 therein from the escapement lever 47, the segmental head being ermitted to drop slightly so that the wheels 119 will be free from the carrying segments 129, but such downward movement is not suflicient to effect an engagement between the wheels 119 and the racks 100, hence the totalizer wheels have no dragging engagement across the teeth of either the carrying segments 129 or the racks 100. As stated before, the particular totalizer under control of the lever 505 will be moved into position over the acks when the handle is being pulled forwrrd, and in this inward movement the frame 49 is in its uppermost positionthat is the totalizer is not in mesh with the racks. To avoid interruption to this movement on the part of the segments 129, I prefer to widen the teeth of said'segments 129 (as shown in Fig. 3*), so as to avoid any spaces between them which might permit the totalizer wheels, which are now free, to rotate (they now'being unrestrained and 513).

In the applica on and patent aforesaid, the teeth of the s ments 129 are wider than the width of the segment plates. There is sufiieient clearance between the widened teeth of the se ments in the present construction and tfie totalizer wheels, to permit a free mdvement of the totalizer wheels into engagement with their respective carrying segments 129.

k In addition to the selective control of the totalizers by the laterally moving paper carriage, I provide means for the manual selection and positioning of the totalizers, which means, as shown in Fig. 9, consists of a rod 70 mounted in the framing of the machine and carrying a head 71 and a crank arm 75 on its forward end, which head and rod are held forwardly by a spring 72. 73 is an indicator slidingly mounted on the rod 70 co5perating with a scale 76 mounted on the framing of the machine and marked with numerals 1, 2 and 3 indicating the first (lowermost), second (middle), or third (uppermost) totalizer under control of the lever 505 or in position over the actuating racks. This arm 70 cotiperates with a bar54 mounted in guiding projections 55 extending from the framing of the machine, with the end of which cotiperates the restoring block 53 when the carriage is moved left wardly. The bar 54 is provided with a pin or projection 54 which fits in the slot of the rock arm 74. Thus, when the carriage is moved leftwardly, the arm 74 is rocked and with it the rod 70. A rod 70 is mounted in suitable bearings under the top plate of the typewriting machine and extends rear wardly and is provided with a rock arm 70 at its rear end which is connected by a,

link 70? to the frame 500; thus, by grasping the handle 75, the rod may be rotated so as to lift the frame 500 and the totalizer-s to their elevated position, the springpressed pawl 515 permitting this. If the uppermost totalizer is in position to be moved over the actuating racks, the frame 500 can be elevated to the second position or the first position, as desired. 70 indicates an arm extending from the rod 70 and engaging the plate 46, the purpose of this being to permit the manual operation of the escapement lever 47 by pushing the rod 70 inwardly to release a totalizer which ,may be over the actuatingracks so as to permit its lateral movement" to normal position, after which, when the rod 70 is released and the escapement lever rocks in the opposite direction, the next highest totalizer will be brought under control of the lever 505. Of. course, if the totalizer is not located over the actuating racks, the operation of the escapement by pushing in the rod 70, will result in dropping the frame 500 to the second or third position to place the middle or uppermost totalizers under control of the lever 500. I

From the above, it will be seen that the totalizers are under control of the paper carriage and also under manual control, the leftward movement of the paper carriage causing the totalizers to successively drop into position, or the successive operation of pushing the rod 70 inwardly producing a like result. Also, that the restoration of the totalizcrs to normal position, that is, by raising them, is under control ot' the paper carriage by virtue of the projection 53 and the rod and its connections, or the handle 75 may be operated manually.

The manner of introducing items into the .F QtIWaICl totalizers when the same are positioned over the racks, or taking totals there from, the construction and operation of the carrying mechanism. multiplying mocha-- nism including the totalizer wheels 268 their 'zsociate carrying mechanism, and other parts illustrated in the drawings, are the same as those illustrated and described in the aforesaid patent and application, and therefore I do not deem it necessary to give an extended dt'iscriptitm of the same here. I will also state that the particular construc tion herein shown and described for manually operating the escapement mechanism to bring the. totalizers successively under control of the lever 505 and for manually restoring the totalizers to their normal or first position, is disclosed in an application tiled by'Huliei-t Hopkins May 11, 1908, se rially numbered 432,166; and I therefore make no claim to the same in this application.
